Abstract

A diagnosis device having a device for producing a series of images, such as a computer tomography device or an ultrasound device. There is also a device for the passive movement of an object and a device that can be stereotactically moved independent of the passive movement object, wherein this stereotactial movement object can be driven by a motor. These two devices can be arranged on or in the diagnosis device to perform a treatment or examination. By controlling the diagnosis device, it is possible to produce a series of images in real time during a passive movement of an object or of the device for performing a treatment or examination.
